Btrfs: make show_options result match actual option names

2009-05-14T18:00:34Z

The notreelog and flushoncommit mount options were being printed slightly differently. Signed-off-by: Sage Weil Signed-off-by: Chris Mason

Btrfs: Fix a bunch of printk() warnings.

2009-04-27T12:37:49Z

Just happened to notice a bunch of %llu vs u64 warnings. Here's a patch to cast them all. Signed-off-by: Joel Becker Signed-off-by: Chris Mason

Btrfs: try to keep a healthy ratio of metadata vs data block groups

2009-04-24T19:46:02Z

This patch makes the chunk allocator keep a good ratio of metadata vs data block groups. By default for every 8 data block groups, we'll allocate 1 metadata chunk, or about 12% of the disk will be allocated for metadata. This can be changed by specifying the metadata_ratio mount option. This is simply the number of data block groups that have to be allocated to force a metadata chunk allocation. By making sure we allocate metadata chunks more often, we are less likely to get into situations where the whole disk has been allocated as data block groups.

btrfs: use memdup_user()

2009-04-21T03:02:50Z

Remove open-coded memdup_user(). Note this changes some GFP_NOFS to GFP_KERNEL, since copy_from_user() may cause pagefault, it's pointless to pass GFP_NOFS to kmalloc(). Signed-off-by: Li Zefan Signed-off-by: Al Viro

Btrfs: add flushoncommit mount option

2009-04-02T20:59:01Z

The 'flushoncommit' mount option forces any data dirtied by a write in a prior transaction to commit as part of the current commit. This makes the committed state a fully consistent view of the file system from the application's perspective (i.e., it includes all completed file system operations). This was previously the behavior only when a snapshot is created. This is used by Ceph to ensure that completed writes make it to the platter along with the metadata operations they are bound to (by BTRFS_IOC_TRANS_{START,END}).

Btrfs: notreelog mount option

2009-04-02T20:49:40Z

Add a 'notreelog' mount option to disable the tree log (used by fsync, O_SYNC writes). This is much slower, but the tree logging produces inconsistent views into the FS for ceph. Signed-off-by: Sage Weil Signed-off-by: Chris Mason

Btrfs: introduce btrfs_show_options

2009-04-02T20:46:06Z

btrfs options can change at times other than mount, yet /proc/mounts shows the options string used when the fs was mounted (an example would be when btrfs determines that barriers aren't useful and turns them off.) This patch instead outputs the actual options in use by btrfs. Signed-off-by: Eric Paris Signed-off-by: Chris Mason
